# Slackware build script for rplay

# Written by Andrew Rowland <darowland@ieee.org>

# 20220410 bkw: Modified by SlackBuilds.org, BUILD=2:
# - do not install headers executable in /usr/include.
# - remove useless INSTALL.generic from doc dir, rename
#   useful INSTALL to something more descriptive.
